How It Works
Blended Trial Starts aggregates trial activation events reported by each connected advertising platform. When a user starts a free trial that’s attributed to an ad within the platform’s attribution window, each platform records a trial start event. This metric sums those events across Meta, Google, and TikTok to give you a unified view of trial acquisition performance.
